Our state-of-the-art, fully-integrated manufacturing facility affords us complete control over the manufacturing process, right from product conceptualization phase to micro-product developmental stage, leading to ultimate customer satisfaction.

Capitalizing on the unique electrical and thermal characteristics of natural mica, Ruby Mica has developed a special insulation system catering to the high-voltage motor and generator industry. These high-performance materials have excellent workability with dielectric and thermal properties to match. Starting from the subtle techniques of mica-taping on conductor coils to the VPI process, our products are fine-tuned to perform to exacting parameters.

Over the years we have emerged as a one-stop shop for complete high-voltage rotating machine insulation systems. Our status as an approved vendor to large corporates like Indian Railways (Chittaranjan Locomotive Works, Diesel Modernization Works), Bharat Heavy Electricals Limited (Bhopal & Haridwar), and others, bears strong testimony of our capability, expertise and commitment to quality. A highly-reliable product and honest pricing-policy comes as standard when you deal with us.
